I have a B3200 with the 60 iinch mmm and have not had good sucess with it either...actually to the point of finding a 72 inch which i am going after tomorrow. The adjustment wheels are too close together as far as I am concerned and the fact that they dont swivel wears them out quicly. My mower is not 2 years old the the rear wheels on the deck have worn to the point the ribs are gone...and if you look up the cost they are ridiculously priced. I have tried and currently have the deflector shield open and that has helped somewhat but still the quality isnt what I would expect. I am getting a 72 inch deck primarily for the difference in the wheels being all outboard rather then the two close together under the tractor. So I may have just made the problem 72 inches wide rather than 60....but will report in when I get it mounted...I mow a combination of fescue and bermudia grass...
